Imperator,
In theory I would say yes.
But whether Ball Zingers in general work as everybody here says they do, I cannot say. I just made it recently,
and the results don’t really seem to manifest them as of yet.
A lot of the “effects” people report here can be put in the same category as placebo’s: because you use something/some method also makes it work, just like a placebo does. Still, if it works for you, who cares if it is caused by suggestion!
My ball zinger delivers some voltage (I measured 0.3 to 0.5 Volts between the copper and zinc when in operation). When I wear it for a whole day, the zinc parts leave some gray stuff on my skin…. Zinc is known to help rise levels of testosterone, and I suspect that the dissolved zinc migrates into your body and has a chemical effect (apart from the generated voltage)
In this respect I wonder if using a small foto-battery (12 V) and applying it using the zinc and copper as electrodes would deliver better results.
The thing that stopped me from doing this, is that it appears that voltages over 1.5 or so change the permeability of cell membranes. Not a good thing I suspect, but it would really “zing” your balls :)
